Jiejia Weichuang and Zhongda developed the first mass production type ZnO-based MOCVD in China

Recently, Shenzhen Jiejiawei Innovation Energy Equipment Co., Ltd. of Guangdong Province successfully developed the first mass production MOCVD equipment dedicated to the growth of large-scale high-quality ZnO semiconductor transparent conductive film materials.

The ZnO growth equipment is mainly small research equipment such as MBE, MOCVD, sputtering machine and PLD, and the production cost is relatively high. Among them, MOCVD equipment adopts rapid film formation speed, large area, uniform, multi-chip growth, and conforms to industrial development. Claim. However, the current method of mass production of ZnO transparent electrodes by mass production type MOCVD equipment is still blank in the domestic and even the entire LED industry.

Jiejiawei called its mass-production MOCVD equipment developed in cooperation with Foshan Research Institute of Sun Yat-sen University. The ZnO-based transparent conductive film prepared by this equipment can be used to make transparent electrodes of super bright LED chips to enhance light extraction efficiency. The complete set of technology can be used to produce GaN-based epitaxial wafers with various illuminating light levels up to 130 lm/w and high-intensity high-brightness illumination levels, and LED chips of various sizes, which are used in downstream LED indoor and outdoor lighting products, which will help LEDs. Manufacturing companies improve product quality and reduce product prices. It is of great significance for the smooth development of the LED industry demonstration and promotion project and the accelerated acceleration of LED into civilian lighting.
 
At present, the patent on ZnO is mainly focused on the application of ZnO transparent conductive film in optoelectronic devices and solar cells. ZnO is used as a transparent electrode for LEDs. Most of the patents focus on improving the ohmic contact interface properties through surface treatment and process technology and improving the tunneling probability by epitaxial growth to improve the tunneling probability. However, MOCVD prepares large-scale ZnO materials. There are still relatively few patents.

Jiejia Weichuang is a manufacturer of special equipment for photovoltaic equipment and green energy industry. It has been paying attention to the development of MOCVD technology at home and abroad. Some of the GaN-MOCVD equipments involved in project research and development personnel have been engaged in fifteen "863" projects for a long time. The research of the film machine has undertaken the research and development of the heart part of the reactor, obtained the test certificate, and was encouraged by the leaders of the Ministry of Science and Technology. In order to expand the company's application market in the optoelectronics industry such as LED lighting, Jiejia Wei is constantly looking for partners in optoelectronics.
